For completeness, below are my analysis notes associated with the previous image:


Must be either INVINCIBLE or INDEFATIGABLE Class Battlecruiser by silhouette – triple funnel (fwd higher) with aft funnel ahead of aft mast; fwd and aft mast-mounted fire control positions; single turret on fo’c’sle although unable to distinguish wing and aft turrets in this view; fo’c’sle carried aft approx 2/3 of length. 

NB INDEFATIGABLE Class was 2nd ship of 1908 Programme intended to improve and develop on INVINCIBLE Class but became a virtual design repeat.

War service of relevant classes indicates 3 possible candidates1,2 (2 x 1905 Programme and 1 x 1908 Programme) in E Med at the same time as GARTH CASTLE:

INDOMITABLE – Med Fleet (2BCS) from 1913; hunted Goeben and Breslau (icw INFLEXIBLE and rest of Med Fleet in Aug 14) before blockading Dardanelles; bombarded outer Dardanelles forts on 3 Nov 14 icw INDEFATIGABLE before returning to Grand Fleet in Rosyth in Dec 14.


INFLEXIBLE – After Battle of Falklands, relieved INDEFATIGABLE as Flagship of CinC Med Fleet; bombarded outer Dardanelles forts on 19 Feb, 15 and 19 Mar. Recorded as being in Malta for repairs to mine damage suffered on 19 Mar 15 and repaired by May 15, then returning to Rosyth to join the Grand Fleet (3BCS).

INDEFATIGABLE – Joined Med Fleet in Dec13; bombarded Cape Helles 3 Nov 14 and became Flagship of CinC Med Fleet (Adm Carden) until Jan 15 when relieved by INFLEXIBLE. Short refit in Malta before returning to the Grand Fleet (2BCS) in Feb 15. Sunk at Jutland 31 May 16.


Key Class distinguishing features visible – INVINCIBLE Class carried a single large cutter behind the mast, deployed by aft facing boom davits mounted on the aft tripod mast. On INDEFATIGABLE Class, the cutter is mounted ahead of the aft tripod mast with forward facing boom davits and they carried additional whalers mounted on davit arms adjacent to the mast. In this image, both starboard boats can be seen being deployed.


Camouflage paint scheme3,4 - In 1914, Professor JG Kerr (Glasgow University, Professor of Zoology) suggested to the Admiralty a form of disruptive camouflage which he called "parti-colouring" and also included a system of “Compensating Shading”, based on colouration patterns observed in nature. A general order to the British fleet issued on 10 November 1914 advocated use of Kerr's principle. It was applied in various ways to British warships such as HMS IMPLACABLE where officers noted that the pattern "increased difficulty of accurate range finding". However following Churchill's departure from the Admiralty, after the failure of the Gallipoli Campaign, the Royal Navy reverted to plain grey paint schemes until the introduction later in the war of “Dazzle” paint schemes.


Given the available candidates and based on the configuration of the boats carried on the aft superstructure, assessment is that this is HMS INDEFATIGABLE. Additionally, given the sinking of INDEFATIGABLE at Jutland in ‘16, the paint scheme in this image must be an early example of Kerr“Parti-colouring” camouflage rather than one of the later Wilkinson “Dazzle”schemes.

Additional Research Point: What is the vessel in background?

Assess that stern visible with aft fire control position, aft mast, gap to funnel, small gap with poss fwd funnel tight to foremast visible above stern of INDEFATIGABLE.

Profile does not fit RN or Fr Capital Ships, Monitors or Cruisers, so assess as probable 2 funnel Destroyer.

Check Fleet lists for Jan/Feb 15 for possible options.

Attached is a photograph which I believe to be of HMS INDEFATIGABLE taken at some point between December 1914 and February 1915. The image has been digitally 'tidied up' to remove some damage evident in the original.
The original is from my grand-mother's photo album which is available to view in this post: (page 7 of Pt1).

HMS Indefatigable was a battlecruiser of the Royal Navy and the lead ship of her class. Her keel was laid down in 1909 and she was commissioned in 1911. She was an enlarged version of the earlier Invincible-class battlecruisers with a revised protection scheme and additional length amidships to allow her two middle turrets to fire on either broadside.

When the First World War began, Indefatigable was serving with the 2nd Battlecruiser Squadron (BCS) in the Mediterranean, where she unsuccessfully pursued the battlecruiser Goeben and the light cruiser Breslau of the German Imperial Navy as they fled toward the Ottoman Empire. The ship bombarded Ottoman fortifications defending the Dardanelles on 3 November 1914, then, following a refit in Malta, returned in February to the United Kingdom where she rejoined the 2nd BCS.

Indefatigable was sunk on 31 May 1916 during the Battle of Jutland, the largest naval battle of the war. Part of Vice Admiral Beatty's Battlecruiser Fleet, she was hit several times in the first minutes of the "Run to the South", the opening phase of the battlecruiser action. Shells from the German battlecruiser Von der Tann caused an explosion ripping a hole in her hull, and a second explosion hurtled large pieces of the ship 200 feet (61 m) in the air. Only two of the crew of 1,017 survived.

Design and description

Right elevation and deck plan as depicted in Brassey's Naval Annual 1915

No battlecruisers were ordered after the three Invincible-class ships until Indefatigable became the lone battlecruiser of the 1908–09 Naval Programme. A new Liberal Government had taken power in January 1906 and demanded reductions in naval spending, and the Admiralty submitted a reduced programme, requesting dreadnoughts but no battlecruisers. The Cabinet rejected this proposal in favor of two outmoded armoured cruisers but finally acceded to a request for one battlecruiser instead, after the Admiralty pointed out the need to match the recently published German naval construction plan and to maintain the heavy gun and armour industries. Indefatigable's outline design was prepared in March 1908, and the final design, slightly larger than Invincible with a revised protection arrangement, was approved in November 1908. A larger design with more armour and better underwater protection was rejected as too expensive.[4]

The ship had an overall length of 590 feet (179.8 m), a beam of 80 feet (24.4 m), and a draught of 29 feet 9 inches (9.1 m) at deep load. She normally displaced 18,500 long tons (18,800 t) and 22,130 long tons (22,490 t) at deep load.[5] Her turbines were designed to produce a total of 43,000 shaft horsepower (32,000 kW), but reached over 55,000 shp (41,000 kW) during sea trials in 1911. She was designed for 25 knots (46 km/h; 29 mph), but reached 26.89 knots (49.80 km/h; 30.94 mph) during trials.[6]

Indefatigable's main armament was eight breech-loading BL 12-inch Mark X guns mounted in four hydraulically powered twin turrets. Two turrets were mounted fore and aft on the centreline, identified as 'A' and 'X' respectively. The other two were wing turrets mounted amidships and staggered diagonally: 'P' was forward and to port of the centre funnel, while 'Q' was situated starboard and aft. 'P' and 'Q' turrets had some limited ability to fire to the opposite side. Her secondary armament consisted of sixteen BL 4-inch Mark VII guns positioned in the superstructure.[7] She mounted two 18-inch (450 mm) submerged torpedo tubes, one on each side aft of 'X' barbette, and twelve torpedoes were carried.[8]

Indefatigable was unique among British battlecruisers in having an armoured spotting and signal tower behind the conning tower, protected by 4 inches (102 mm) of armour. However, the spotting tower was of limited use, as its view was obscured by the conning tower in front of it and the legs of the foremast and superstructure behind it.[9] During a pre-war refit, a 9-foot (2.7 m) rangefinder was added to the rear of the 'A' turret roof, and this turret was equipped to control the entire main armament as an emergency backup for the normal fire-control positions.[10]

Wartime modifications

Indefatigable received a single QF 3-inch 20 cwt[Note 1] anti-aircraft gun on a high-angle Mark II mount in March 1915,[11] with a maximum depression of −10° and a maximum elevation of +90°. It fired a 12.5-pound (5.7 kg) shell at a muzzle velocity of 2,500 ft/s (760 m/s) and a rate of fire of 12–14 rounds per minute. It had a maximum effective altitude of 23,500 ft (7,200 m)[12] and was provided with 500 rounds. All of her 4-inch guns were enclosed in casemates and given gun shields during a refit in November 1915 to better protect the gun crews from weather and enemy action, although two aft guns were removed at the same time.[11]

She received a fire-control director between mid-1915 and May 1916 that centralized fire control under the director officer who now fired the guns. The turret crewmen merely had to follow pointers transmitted from the director to align their guns on the target. This greatly increased accuracy since the ship's roll no longer dispersed the shells as each turret fired on its own; also, the fire-control director could more easily spot the fall of the shells.[13]


Early career

Indefatigable was laid down at the Devonport Dockyard, Plymouth on 23 February 1909. She was launched on 28 October 1909 and was completed on 24 February 1911.[14] Upon commissioning, Indefatigable served in the 1st Cruiser Squadron, which in January 1913 was renamed the 1st Battlecruiser Squadron (BCS). In December 1913, she transferred to the Mediterranean, where she joined the 2nd Battlecruiser Squadron.[15]

Pursuit of Goeben and Breslau


Indefatigable, accompanied by Indomitable and under the command of Admiral Sir Archibald Berkeley Milne, encountered the German ships Goeben and Breslau on the morning of 4 August 1914, which were headed east after a cursory bombardment of the French Algerian port of Philippeville. Britain and Germany were not yet at war, so Milne turned to shadow the Germans as they headed back to Messina to recoal. All three battlecruisers had problems with their boilers, but Goeben and Breslau were able to break contact and reached Messina by the morning of the 5th. By this time Germany had invaded Belgium and war had been declared, but an Admiralty order to respect Italian neutrality and stay more than six miles (10 km) from the Italian coast precluded entering the Strait of Messina, from which they could have observed the port directly. Therefore Milne stationed Inflexible and Indefatigable at the northern exit of the strait, expecting the Germans to break out to the west where they could attack French troop transports. He stationed the light cruiser Gloucester at the southern exit, and sent Indomitable to recoal at Bizerte, where she was ready for action in the Western Mediterranean.[16]

The Germans sortied from Messina on 6 August and headed east, toward Constantinople, trailed by Gloucester. Milne, still expecting Rear Admiral Wilhelm Souchon to turn west, kept the battlecruisers at Malta until shortly after midnight on 8 August when he set sail at a leisurely 12 knots (22 km/h; 14 mph) for Cape Matapan, where Goeben had been spotted eight hours earlier. At 2:30 p.m.[Note 2] he received an incorrect message from the Admiralty stating that Britain was at war with Austria-Hungary. War would not actually be declared until 12 August, and the order was countermanded four hours later, but Milne gave up the hunt for Goeben, following his standing orders to guard the Adriatic against an Austrian breakout attempt. On 9 August Milne was given clear orders to "chase Goeben which had passed Cape Matapan on the 7th steering north-east."[17] Milne still did not believe that Souchon was heading for the Dardanelles, and so he resolved to guard the exit from the Aegean, unaware that the Goeben did not intend to come out.[17]

On 3 November 1914, Churchill ordered the first British attack on the Dardanelles following the commencement of hostilities between Ottoman Turkey and Russia. The attack was carried out by Indomitable and Indefatigable, as well as the French pre-dreadnought battleships Suffren and Vérité. The intention of the attack was to test the fortifications and measure the Turkish response. The results were deceptively encouraging. In a twenty-minute bombardment, a single shell struck the magazine of the fort at Sedd el Bahr at the tip of the Gallipoli peninsula, displacing (but not destroying) 10 guns and killing 86 Turkish soldiers. The most significant consequence was that the attention of the Turks was drawn to strengthening their defences, and they set about expanding the mine field.[18] This attack actually took place before Britain's formal declaration of war on 6 November against the Ottoman Empire. Indefatigable remained in the Mediterranean until she was relieved by Inflexible on 24 January 1915 and proceeded to Malta for a refit; she then sailed to England on 14 February and joined the 2nd BCS upon her arrival. She was the temporary flagship of the 2nd BCS during April–May 1916, while her half-sister HMAS Australia was under repair after having collided with her other half-sister HMS New Zealand.[19]

Battle of Jutland

Main article: Battle of Jutland

On 31 May 1916, the 2nd BCS consisted of New Zealand (flagship of Rear Admiral William Christopher Pakenham) and Indefatigable.[20] The squadron was assigned to Admiral Beatty's Battlecruiser Fleet which had put to sea to intercept a sortie by the High Seas Fleet into the North Sea. The British were able to decode the German radio messages and left their bases before the Germans put to sea. Hipper's battlecruisers spotted the Battlecruiser Fleet to their west at 3:20 p.m., but Beatty's ships did not spot the Germans to their east until 3:30. Two minutes later, he ordered a course change to east south-east to position himself astride the German's line of retreat and called his ships' crews to action stations. He also ordered the 2nd BCS, which had been leading, to fall in astern of the 1st BCS. Hipper ordered his ships to turn to starboard, away from the British, to assume a south-easterly course, and to reduce speed to 18 knots (33 km/h; 21 mph) to allow three light cruisers of the 2nd Scouting Group to catch up. With this turn Hipper was falling back on the High Seas Fleet, then about 60 miles (97 km) behind him. Around this time Beatty altered course to the east as it was quickly apparent that he was still far too north to cut off Hipper.[21]

HMS Indefatigable sinking after being struck by shells from the German battlecruiser Von der Tann

This began what was to be called the "Run to the South" as Beatty changed course to steer east south-east at 3:45, paralleling Hipper's course, now that the range closed to under 18,000 yards (16,000 m). The Germans opened fire first at 3:48, followed by the British. The British ships were still in the process of making their turn as only the two leading ships, Lion and Princess Royal, had steadied on their course when the Germans opened fire. The British formation was echeloned to the right with Indefatigable in the rear and furthest to the west, and New Zealand ahead of her and slightly further east. The German fire was accurate from the beginning, but the British overestimated the range as the German ships blended into the haze. Indefatigable aimed at Von der Tann and New Zealand targeted Moltke while remaining unengaged herself. By 3:54, the range was down to 12,900 yards (11,800 m) and Beatty ordered a course change two points to starboard to open up the range at 3:57. Around 4:00, Indefatigable was hit by two or three shells from Von der Tann around the rear turret. She fell out of formation to starboard and started sinking toward the stern and listing to port. Her magazines exploded at 4:03 after more hits, one on the forecastle and another on the forward turret. Smoke and flames gushed from the forward part of the ship and large pieces were thrown 200 feet (61.0 m) into the air.[22] The most likely cause of her loss was a deflagration or low-order explosion in 'X' magazine that blew out her bottom and severed the steering control shafts, followed by the explosion of her forward magazines from the second volley.[23] Von der Tann fired only fifty-two 28 cm (11 in) shells at Indefatigable before she exploded. Of her crew of 1,017, only two survived, rescued by the German torpedo boat S68.[24] While still in the water, the two survivors found the ship's badly wounded captain, C. F. Sowerby, who died before they could be rescued.[25]

Indefatigable today

Indefatigable, along with the other Jutland wrecks, was belatedly declared a protected place under the Protection of Military Remains Act 1986, to discourage further damage to the resting place of 1,015 men.[26] Mount Indefatigable in the Canadian Rockies was named after the battlecruiser in 1917.[27]
